The specific embodiment
Fig. 1 Succinct representation motor-driven hand feeding grinder 10, be designed to the eccentric disc grinding machine herein.Hand feeding grinder 10 has 11 machine casings of representing of a usefulness, and there is a drive motors 12 that has working-spindle 13 its inside, and this main shaft 13 is by means of for example being bearing in 11 li of casings for the bearing 14 of ball bearing pattern.Usually with the mill unit and 13 antitorque connections of main shaft of 15 marks, this unit is driven by means of main shaft 13 and produces an eccentric motion, and can rotate.There are a cover 16, it and 13 axial antitorque being connected of main shaft in mill unit 15.Cover 16 extends with axis 17 coaxial lines of main shaft 13, and a rotor journal 18 is for example arranged in the lower end of Fig. 1, and its eccentric axis 19 is e with the eccentric throw of axis 17, and is parallel to this axis.On rotor journal 18 by bearing 20, ball bearing for example, rotatably mounted have a mill 21.Mill 21 is by a screw 22 that is screwed into 18 li of rotor journals with eccentric axis 19 coaxial lines, interconnects with cover 16 and rotor journal 19 antitorque and axial restraint, and can change by unclamping screw 22.A leather cup 23 that makes the middle cavity sealing is arranged between above the mill 21 in casing 11 and Fig. 1.Manually grinding machine 10 is equipped with an inner dust exhaust apparatus, and a draught fan impeller 24 is wherein arranged, and this impeller 24 remains on the cover 16 antitorquely.Draught fan impeller 24 is positioned at 25 li of chambers, and being right after this chamber is a dust absorption passage 26, and mill has passage and/or through hole 27 to be used for inner dust suction for 21 li.
Attach troops to a unit in being and just can centering on its central axis by second barreling face 30 of this device of second barreling face 30, also promptly center on axis 17 and can stop or discharge selectively usually with the brake apparatus of 35 signs.This layout makes the second barreling face 30, and especially the rotatability of external toothing 32 just can stop or discharge in the machine run duration by means of brake apparatus 35.
Draught fan impeller 24 is arranged on the cover 16 as the parts of inner dust exhaust apparatus antitorquely in the embodiment shown.That has been not so just in the embodiment that another kind is not expressed, draught fan impeller then designs at a fan and puts, this fan cover is arranged on the work optical axis 13 then antitorquely, and has an interior cover with axis 17 off-centre, by means of one with the coaxial bearing of eccentric axis 19 just make a cylindrical shroud that is similar to cover 16 rotatably and axial restraint ground place overlap in this in, mill 21 just releasably is fixed on this cover distolateral by means of screw 22.
Brake apparatus 35 has braking action braking member 36 and operating means 37 that is used to operate braking member 36 in the second barreling face 30.Braking member 36 has a braking surface 38.With this braking surface 38, this braking member 36 just can plane earth acts on the face 39 of attaching troops to a unit of the second barreling face 30 and is used to make the second barreling face 30 to stop the rotation, and wherein this face 39 especially is designed to the outside of external toothing 32.The second barreling face 30 is arranged in outer and round the first barreling face 28, and two faces just were arranged in one basically and publicly were in the diametric plane with axis 17 working-spindle 13 this moment.The face that is designed to outer surface 39 of the second barreling face 30 especially is made up of the outer circumference surface 40 of external toothing 32.
Usually braking member 36 fully is made up of such brake component, and its medial surface that is designed to braking surface 38 can abut against on the surface 39 of attaching troops to a unit of second barreling face 30, especially leans against to make to rotate on the outer circumference surface 40 of external toothing 32 to stop.In simple especially design, braking member 36 comprises a brake band, and this band enwinds the outer circumference surface 40 of external toothing 32 and can be tensioned and is used to stop outer circumference surface 40 rotations.
Operating means 37 has an eccentric lever, has one to be bearing in the 11 li eccentric parts that can swing 41 of casing and a rotor journal 42 on it, and this axle journal is in pack into 43 li in a hole of an end of the braking member 36 that is designed to brake band, for example in noose.There is a handle 44 that is positioned at outside the casing 11 to be used for swinging operation in effect on the eccentric part 41.Design with the operating means 37 of described eccentric lever form should guarantee, makes the braking member 36 that is designed to brake band realize tensioning by means of central part 41 around an about circumference of 180 °.Figure 3 shows that the state that tension position and external toothing 32 stop the rotation.If handle 44 on counter-clockwise direction, turn round about 180 ° to position shown in Figure 2, braking member 36 with the brake band form has just unclamped so, thereby external toothing 32 just do not braked, and therefore it just can center on axis 17, and the while also is its central axis and rotating.
For another embodiment that does not represent, operating means 37 has an operational example as with the braking member 36 of brake band form, the especially magnet of tensioning brake band, for example a kind of electromagnet that can handle.
Another particularity of hand feeding grinder 10 is that the internal gear 31 of external toothing 32 has than the outer tooth ring 29 more numbers of teeth.Number of teeth difference for example can reach 2.This has just caused, when external toothing 32 braking, within it on the ring gear 31 outer tooth ring 29 of barreling every tooth of the just many rotations of 180 ° of eccentric motions, and thereby mill 21 with outer tooth ring 29 just when barreling, produced the rotating speed of mill.The rotating speed of mill 21 for example reaches 417 rev/mins when the frequency of setting that shakes is 10000.
If brake apparatus 35 places application position corresponding to Fig. 3, and connect with drive motors 12, working-spindle 13 and cover 16 just by motor are driven in rotation rotating speed for example about 10000 rev/min together with draught fan impeller 24 and the balance mass that may not illustrate especially herein so.Shown in embodiment the time, working-spindle 13 just directly is transferred on the cover 16.That has been not so just when the unshowned embodiment of another kind, and has also designed a kind of transmission device betwixt.Because this transmission campaign drives mill 21 like this, the rotation around eccentric axis 19 has promptly also taken place except eccentric motion, thereby caused the off-centre of mill 21 to rotatablely move.Because this brake apparatus 35 has initiatively stoped the rotation of external toothing 32, thereby outer tooth ring 29 just can barreling on internal gear 31 when revolution.Mill 21 thereby also force transmission around eccentric axis 19 in this state.
If be not converted to by unclamped state shown in Figure 2 at the moving element 36 of manual grinding machine 10 work schedules by means of operating means 37, external toothing 32 can freely center on axis 17 rotations so, and this is owing to being bearing in by means of bearing 34 on the cover 16.External toothing 32 can the rotation together by the friction of 34 li on bearing.According to coefficient of friction, external toothing 32 produces a relative motion in the direction of rotation opposite with mill 21.The rotating speed of mill 21 depends on the load on the base, also promptly depends on, manually mill 21 and a degree releasable in the above, that for example fixing abrasive disc compresses to a workpiece to be processed by means of the hook lockset of grinding machine 10.The rotating speed of mill 21 also can be according to the condition vanishing.Be exactly dry run to manual grinding machine 10 in this case.
When manual grinding machine 10 runnings of connecting motor, just can be transformed into pressure again by operate brake 35 and drive with this dry run.
Described hand feeding grinder 10 is simple in structure, compact, and both economical.It can be in simple mode by operating lever, and perhaps the embodiment that does not express for another kind can operate a magnet and realize conversion at the machine run duration, and carries out the transition to dry run from forcing to drive continuously.The part as a whole because outer tooth ring 29 is injected on the annular element of mill 21, its advantage be part reduce and structure height also little.In addition, realize that advantageously the expense of barreling transmission is lower, this transmission has comprised outer tooth ring 29 and internal gear 31.
